A Brand New Waterproof Basement for this New Care Home for the Elderly
The building has a 1500m2 basement and the sloping site required a contiguous piled wall, providing foundation support and retaining a high bank. The builders required an effective and guaranteed waterproofing method. The Safeguard Europe solution was agreed, using Type A & Type C waterproofing, in accordance with BS8102.
First, the 1500M2 basement floor slab was prepared by enclosed shot blasting. This was essential because Vandex Super was chosen.
This Swiss made material grows into the concrete, blocking the tiny pores in the material and sealing it against water; ‘In depth’ waterproofing is the end result, much better than merely a surface coating, which may be prone to damaged.
Vandex Super is simply mixed with water to provide an effective waterproofing material.
Even better, the Vandex ingredients stay active after application, being able to re-animate and grow into small cracks and fissures if these occur later.
This self-repairing waterproofing is unique and a remarkable feature of Vandex Super.
Our trained technicians completed this element in just a week long process. The type C part of the work involved supply and installation of 600M2 of Oldroyd XV clear.
This cavity drain membrane was carefully linked into Horsham based Safeguard?s Aqua Drain system. Any water entering the basement is managed through these aqua drains and diverted to waste. With careful planning, we were able to avoid the use of pumping stations on this project.
By using a combination of waterproofing techniques and matching the best materials to each, we succeeded in delivering the finished project; a dry basement, guaranteed with insurance from the Guarantee Protection Insurance Company.
The waterproofing is hidden behind internal blockwork walls, insulation and floor finishes. The client is relying on it doing its job; keeping the basement dry. To achieve this level of quality, on a busy building site, with many different tradesmen working and walking to and fro, is a skill in itself.

As Bryan Hindle CSSW explains “On new build basement waterproofing and refurbishment waterproofing, you have to be aware of the tradesman following you; they can?t be expected to know ‘the do?s and don’ts’ of waterproofing work. To avoid trouble later, effective communication, with a helpful approach is essential.
We held the other contractors hands all the way along, until they had moved beyond any work which could accidentally harm our customer’s waterproofing system.”
Bryan is delighted with the feedback from Richmond, via main contractors Frank Haslem Milan, who appreciated this attention to detail “We really appreciated Brick-Tie Preservation’s professionalism; they moved things on really quickly.” says FHM’s Paul Novel.
We have a short case study video on our You Tube channel, which shows this project, from start to finish.
